Description

Technical Field

[0001] This invention relates to the field of mold changing technology, and more particularly to a dual-station mold changing trolley. Background Technology

[0002] Currently, the common method for changing molds is to use a crane or a mold changing vehicle. However, using a crane involves a large investment cost and is inconvenient to move. Therefore, the more common method is to use a mold changing vehicle. In existing mold changing vehicles, the design is a single workstation, which reduces work efficiency. Furthermore, the drive mechanism of the lifting and pushing mechanism in the mold changing vehicle is located outside the vehicle, which makes the structure of the mold changing vehicle longer, occupies a larger area, and is inconvenient to operate. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a dual-station mold changing trolley, which improves work efficiency. The drive mechanism in the lifting and pushing mechanism is set inside the mold changing trolley, which makes the mold changing trolley structure occupy a small area and is easy to operate.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a dual-station mold changing trolley, including a trolley body, on which a first station and a second station are installed. The first station includes a dual-power mold changing mechanism, which includes a lifting and pushing mechanism and roller mechanisms located on both sides of the lifting and pushing mechanism, and also includes a pushing and pulling mechanism arranged perpendicularly to the dual-power mold changing mechanism. A mold positioning block and a first motor for driving the positioning block to lift are provided between the first station and the second station. The second station has the same structure as the first station.

[0005] Furthermore, the lifting and pushing mechanism includes a first guide rail and a lifting mechanism. The lifting mechanism includes a fixed frame, a fixed plate is installed on the fixed frame, a hydraulic cylinder is installed on the fixed plate, a lifting plate is fixedly connected to the piston rod of the hydraulic cylinder, a second guide rail is installed on the lifting plate, and also includes a mold hook located on the second guide rail and a second motor that drives the mold hook to slide within the second guide rail. The first guide rail is connected to the second guide rail after it has been raised.

[0006] Furthermore, the roller mechanism includes a mounting plate on which a driven shaft is mounted. One end of the driven shaft is equipped with a plurality of rollers and a first gear located on one side of the rollers. The other end of the driven shaft is equipped with a second gear. The mechanism also includes a drive shaft, a third motor for driving the drive shaft, and a chain. The third gear is mounted on the drive shaft, and the second gear and the third gear are connected by a chain.

[0007] Furthermore, the push-pull mechanism includes a third guide rail and a fourth guide rail, which are connected together. A slider and a fourth motor that drives the slider to slide on the third and fourth guide rails are provided on the third guide rail. A cylinder that drives the fourth guide rail to move horizontally is provided on one side of the fourth guide rail.

[0008] Furthermore, the bottom of the vehicle body is equipped with rollers that can move on a slide rail.

[0009] Furthermore, the hydraulic cylinder is fixed to the mounting plate by screws.

[0010] The beneficial effects of this invention are: by setting up a dual workstation on the mold changing trolley, the working efficiency of the mold changing trolley is improved; by setting the drive mechanism in the push-pull mechanism inside the mold changing trolley, the mold changing trolley structure occupies a small area, making it convenient for workers to operate the mold changing trolley; and by adopting a dual-power mold changing mechanism, the efficiency of mold changing is improved.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 and 2As shown, a dual-station mold changing trolley includes a body 1, on which a first station and a second station are mounted. The first station includes a dual-power mold changing mechanism 2, which includes a lifting and pushing mechanism 21 and roller mechanisms 22 located on both sides of the lifting and pushing mechanism 21. It also includes a pushing and pulling mechanism 3 perpendicularly arranged to the dual-power mold changing mechanism 2. A mold positioning block 4 and a first motor driving the positioning block 4 to lift are provided between the first station and the second station. The second station has the same structure as the first station. When the dual-station mold changing trolley starts working, the lifting and pushing mechanism 21 rises to pull the mold to be replaced from the mold library onto the roller mechanism 22. The lowering and pulling mechanism 21 is lowered, and the mold is driven to continue moving through the roller mechanism 22 until it is completely located on the dual-station mold changing trolley and stops working. At this time, the pushing and pulling mechanism 3, which is perpendicular to the dual-power mold changing mechanism 2, drives the mold to the second station. The first motor drives the positioning block 4 to rise and position the mold on the first and second stations to prevent the mold from shifting during operation. By setting up two stations on the mold changing trolley, the working efficiency of the mold changing trolley is improved. The drive mechanism in the lifting and pulling mechanism is set inside the mold changing trolley, which makes the mold changing trolley structure occupy a small area and facilitates the operation of the mold changing trolley by the staff. Moreover, the use of the dual-power mold changing mechanism 2 improves the efficiency of mold changing.

[0019] Based on this, such as Figure 2 and 3 As shown, the lifting and pushing mechanism 21 includes a first guide rail 211 and a lifting mechanism 23. The lifting mechanism 23 includes a fixed frame 231, a fixed plate 232 mounted on the fixed frame 231, a hydraulic cylinder 233 mounted on the fixed plate 232, a lifting plate 234 fixedly connected to the piston rod of the hydraulic cylinder 233, a second guide rail 24 mounted on the lifting plate 234, and also includes a mold hook 241 located on the second guide rail 24 and a second motor 24 for driving the mold hook 241 to slide within the second guide rail 24. 2. The first guide rail 22 is connected to the second guide rail 24 when it is raised. When the dual-station mold changing trolley starts working, the hydraulic cylinder 233 drives the lifting plate 234 to rise, so that the first guide rail 22 is connected to the second guide rail 24. The second motor 242 drives the mold hook 241 to run on the first guide rail 211 and the second guide rail 24. The mold hook 241 pulls the mold out of the mold magazine and runs it on the first guide rail 211 and the second guide rail 24 onto the roller mechanism 22. The lifting and pushing mechanism 21 adopted improves the mold running efficiency.

[0020] Based on this, such as Figure 4As shown, the roller mechanism 22 includes a mounting plate 221, on which a driven shaft 222 is mounted. One end of the driven shaft 222 is mounted with multiple rollers 223 and a first gear 224 located on one side of each roller 223. The other end of the driven shaft 222 is mounted with a second gear 225. It also includes a drive shaft, a third motor 226 driving the drive shaft, and a chain 228. A third gear 227 is mounted on the drive shaft. The second gear 225 and the third gear 227 are connected by the chain 228. The lifting and pushing mechanism 21... The mold is pulled onto the roller mechanism 22, and the roller mechanism 22 starts to work. The third motor 226 drives the drive shaft. The rotation of the drive shaft drives the third gear 227, chain 228 and second gear 225 to rotate. The rotating second gear 225 drives the driven shaft 222 to rotate through the chain 228 and the first gear 224. The rotation of the driven shaft 222 drives the multiple rollers 223 installed at one end of the driven shaft 222 to rotate. The rotation of the rollers 223 causes the mold to move horizontally onto the push-pull mechanism 3. The roller mechanism 22 improves the operating efficiency of the mold.

[0021] Based on this, such as Figure 5 As shown, the push-pull mechanism 3 includes a third guide rail 31 and a fourth guide rail 32, which are connected. A slider 33 and a fourth motor 34 are provided on the third guide rail 31 to drive the slider 33 to slide on the third guide rail 31 and the fourth guide rail 32. A cylinder 35 is provided on one side of the fourth guide rail 32 to drive the fourth guide rail 32 to move horizontally. When the lifting push-pull mechanism 21 is working, the cylinder 35 drives the fourth guide rail 32 to move horizontally to the side away from the third guide rail 31, so that the lifting mechanism 23 rises to transport the mold. When the lifting mechanism 23 stops working, the cylinder 35 drives the fourth guide rail 32 to move horizontally to connect with the third guide rail 31. The fourth motor 34 drives the slider 33 and the mold located on the slider 33 to slide on the third guide rail 31, transporting the mold to the second work station, thereby improving work efficiency.

[0022] Based on this, such as Figure 1 As shown, the bottom of the vehicle body 1 is provided with rollers 11 that can move on the slide rail; the rollers facilitate the movement of the vehicle body 1 and achieve the effect of improving work efficiency.

[0023] Based on this, such as Figure 3 As shown, the hydraulic cylinder 233 is fixed to the fixing plate 232 by screws; the hydraulic cylinder 233 fixed by screws is easy for workers to disassemble and improves the workers' work efficiency.

It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
